Ics Triplex T8461 Trusted TMR 24/48Vdc Digital Output Module

Description

• • Performance Parameters
    • Response & Update Speeds: The output turn-on and turn-off delay is 0.5ms, and the sample update time is also 0.5ms. It achieves a 1ms sequence of events resolution and a timestamp accuracy of ±0.5ms, which can accurately record the timing of output signal changes.
    • Protection & Capacitance: It is equipped with electronic latching short-circuit protection for outputs. For Release 3.5, the pre-release maximum capacitance is 30 – 55μF, and the release stage can achieve a capacitance of at least 3500μF when the current is 0.75A.
  • Physical & Environmental Parameters
    • Physical Dimensions: It has dimensions of 266mm in height, 31mm in width and 303mm in depth, and weighs 1.285kg, which is convenient for installation in standard industrial racks.
    • Temperature Adaptability: It operates stably within a temperature range of -5°C to 60°C, and can be stored in an environment with temperatures ranging from -25°C to 70°C.
    • Humidity Tolerance: It works normally in an environment with 5% – 95% relative humidity without condensation, adapting to the humidity variations of most industrial sites.
• Function Features
  • Triple Modular Redundancy Architecture: The fully triplicated circuit design forms the core of its fault tolerance. Three independent circuits perform the same operations and cross-verify results. Any single-circuit fault is isolated automatically, which ensures the module continues to output accurate control signals without being affected by single-point failures.
  • Optional Line Monitoring: The module is configured with optional line monitoring capabilities that can actively detect open-circuit and short-circuit faults in field wiring and loads. This function enables maintenance personnel to identify and address wiring problems promptly without disrupting the overall system operation.
  • Independent Power Group Design: The 40 output channels are divided into 5 independent power groups with 8 channels each. This design prevents faults in one power group from spreading to others, which enhances the overall stability of the module and allows for targeted maintenance.
  • Hot-Swappable Capability: The module supports hot-swappable operation. Maintenance personnel can replace the faulty module online without shutting down the entire control system. This feature significantly reduces system downtime and improves the efficiency of equipment maintenance and troubleshooting.
  • Strong Output Protection: It is equipped with electronic latching short-circuit protection for outputs. When a short-circuit occurs in an output channel, the protection mechanism activates immediately to latch the fault state, which prevents the module and connected field devices from being damaged by excessive current.
• Application Scenarios
  • Oil and Gas Industry: It is widely used in emergency shutdown systems and safety interlocking systems for upstream oil exploration platforms, midstream pipeline transportation networks and downstream refining facilities. It controls the opening and closing of valves, the start-stop of pumps and other key equipment. When abnormal pressure or gas leakage is detected, it sends accurate output signals to trigger emergency shutdown procedures and avoid major safety accidents.
  • Chemical Industry: It integrates into the control systems of chemical reaction kettles, storage tanks for hazardous chemicals and pipeline transportation systems. It regulates devices such as flow control valves and emergency cut-off valves. Its stable output ensures that chemical production processes follow preset safety procedures and prevents leakage, explosion and other dangerous incidents caused by equipment misoperation.
  • Power Industry: It is applied in the safety control systems of thermal power plants and nuclear power plants. It controls the operation of boiler auxiliary equipment, steam turbine emergency control components and generator safety interlocking devices. It can quickly output control signals to shut down related equipment when parameters such as temperature and pressure exceed safe limits, which protects expensive power generation equipment and ensures the stability of the power grid.
  • Metallurgical Industry: It is deployed in blast furnace control systems, steel rolling production lines and non-ferrous metal smelting equipment. It controls the start-stop of conveyor belts, the adjustment of smelting temperature control components and the switching of material feeding devices. Its high reliability adapts to the high-temperature and high-dust environment of metallurgical plants and ensures the continuity and safety of the metallurgical production process.
